2. Requirement

- CUDA Toolkit version 1.0 and above. http://www.nvidia.com/object/cuda_get.html

- A GPU capable of running CUDA.

- GLUT http://www.xmission.com/~nate/glut.html (for graphical display)

3. GPU Tested

PBA has been tested on NVIDIA Geforce 9600M GT, 9800 GT, GTX280 and Tesla C1060.

4. Zip Files

The zip files contain all the source codes necessary to use the software. Each also includes a sample Visual Studio project to compute the result for a randomly uniformly distributed set of points.

The project is funded by the National University of Singapore under grant R-252-000-337-112.
